Okay, so about a year ago I made a program that allows the user to put in specs of their car in order to get the best possible wheel and tire setup. The program takes into account:
1) The camber profile of the suspension
2) Camber specs
3) Fender location
4) Fender mods like rolling/pulling and widebody panels
5) Lowering the car statically or with bags
6) Exact tire specs as not every 235/40 R18 fits the same (works with all tire sizes, just making a point)
7) Wheel specs including the thickness from the bead surface of the wheel to the face of the wheel as no wheel that is rated at say 8 inches, is actually 8 inches wide it will be almost 9 from face to face.
The only downside to the original program was it was made in MATLAB, which can't export projects to executables, and requires the user to pay for a licence to just have the coding IDE to run the program. This made all of my work useless in helping the community, until now.
I have now begun porting it over to java, using an IDE called processing, which is a great graphical IDE. It allows me to easily setup a display of what I want, and is more powerful than matlab, which allows me to make the program cleaner and more easily expandable. I am not that far, but I have gotten to a point where the interface is being worked out to make it user friendly, and then I will port over the main part of the program that actually does the calculations and drawing of the wheel setup.
As of this moment I need help from the community, I have some crude measurements of the rear suspension in order to estimate the camber change with compression. If anyone is able to get me actual values for camber with compression I would be greatful. How I want to data is as follow:
Suspension Travel (in.):
-2 in
-1.5 in
-1 in
-0.5 in
Stock ride height
0.5 in
1 in
1.5 in
2 in
2.5 in
3 in
3.5 in
4 in
4.5 in
You get the point, I want values every half inch, until full compression is obtained. I need this for front and rear to allow each wheel to be fit perfectly. As of now my numbers are from me measuring what I was able to for the rear, modeling it in solid works and forcing displacements to see the angles, which gets close but not sure how realistic the results were. Plus I can't measure the front in the same way as there is less room to get up in the front to measure.
Any help would be greatly appreciated!!!
I would like to have the results by the end of next week if at all possible, if you are able to get the data, let me know if you can't meet that deadline but will be able to do it in the next 2 weeks. I need to finish this by January 18 or I will be at a standstill for a while as I won't have time due to the semester starting on the 19th. In the meantime I will be making the interface and the calculations part, and use the dummy values I have to get me by.
Happy Holidays!!!!
